Didnt know about the eyes thing. Thats fucking cool too. I disagree with you on the IQ thing. Being able to think well is huuuuge in cs, that an spatial awareness is what allows amazing clutch plays. Knowing every angle by memory, but also being able to predict exactly where people can be, if they arent in a given spot by a given time etc, while understanding what the best thing to do in your current position, with current weapon, current health, time left etc, is something you can practice, but in most cases in the heat of the moment, it is down to the individual and their brilliance to come out on top, along with skill ofc. IQ ofc only matters up to a point, but most pro cs players at a high level will pass pretty much all physical and mental tests, disregarding boombl4 ofc. Anyone who is dumb and cant read their opponents mid game are the people in mm who cries "OH HOW IS HE THERE" or "OMG HOW HE KNOW ME xd" in voice everytime they die to some super predictable shit, beacuse they are stupid.
